[RFI] Car Advice

[Larry Benko]

There is NO chance that any amateur radio transmitter in a vehicle would 
trip the air bags.  They and the anti-lock brakes are at the top of the 
testing requirements for car manufacturers.  The requirements were 
something like more than 150V/m over the HF and VHF range which means 
you can drive right up to a 100kW FM or TV transmitter and be fine.  
Unfortunately things like fans, windows, and even engine management do 
not have to meet the same requirements.  I believe Ford had 5 
classifications and only things which were likely to kill someone made 
it into the top class.  The stuff at the bottom only needed to not 
interfere with the AM/FM radio in the vehicle. :)  Not sure if all the 
manufacturers met the same requirements but they all don't like 
litigation where death is involved.
